BACKGROUND I. Field

The following description relates generally to wireless communications,and more particularly to relative timing and operation between pagingindicator channel and high speed channels.

II. Background

Wireless communication systems are widely deployed to provide varioustypes of communication content such as, for example, voice, data, and soon. Typical wireless communication systems may be multiple-accesssystems capable of supporting communication with multiple users bysharing available system resources (e.g., bandwidth, transmit power, . .. ). Examples of such multiple-access systems may include code divisionmultiple access (CDMA) systems, time division multiple access (TDMA)systems, frequency division multiple access (FDMA) systems, orthogonalfrequency division multiple access (OFDMA) systems, and the like.Additionally, the systems can conform to specifications such as thirdgeneration partnership project (3GPP), 3GPP long term evolution (LTE),etc.

Generally, wireless multiple-access communication systems maysimultaneously support communication for multiple mobile devices. Eachmobile device may communicate with one or more base stations viatransmissions on forward and reverse links. The forward link (ordownlink) refers to the communication link from base stations to mobiledevices, and the reverse link (or uplink) refers to the communicationlink from mobile devices to base stations. Further, communicationsbetween mobile devices and base stations may be established viasingle-input single-output (SISO) systems, multiple-input single-output(MISO) systems, multiple-input multiple-output (MIMO) systems, and soforth. In addition, mobile devices can communicate with other mobiledevices (and/or base stations with other base stations) in peer-to-peerwireless network configurations.

MIMO systems commonly employ multiple (N_(T)) transmit antennas andmultiple (N_(R)) receive antennas for data transmission. A MIMO channelformed by the N_(T) transmit and N_(R) receive antennas may bedecomposed into N_(S) independent channels, which may be referred to asspatial channels, where N_(S)≤{N_(T),N_(R)}. Each of the N_(S)independent channels corresponds to a dimension. Moreover, MIMO systemsmay provide improved performance (e.g., increased spectral efficiency,higher throughput and/or greater reliability) if the additionaldimensionalities created by the multiple transmit and received antennasare utilized.

MIMO systems may support various duplexing techniques to divide forwardand reverse link communications over a common physical medium. Forinstance, frequency division duplex (FDD) systems may utilize disparatefrequency regions for forward and reverse link communications. Further,in time division duplex (TDD) systems, forward and reverse linkcommunications may employ a common frequency region. However,conventional techniques may provide limited or no feedback related tochannel information.

Referring now to FIG. 1, a wireless communication system 100 isillustrated in accordance with various embodiments presented herein.System 100 comprises a base station 102 that can include multipleantenna groups. For example, one antenna group can include antennas 104and 106, another group can comprise antennas 108 and 110, and anadditional group can include antennas 112 and 114. Two antennas areillustrated for each antenna group; however, more or fewer antennas canbe utilized for each group. Base station 102 can additionally include atransmitter chain and a receiver chain, each of which can in turncomprise a plurality of components associated with signal transmissionand reception (e.g., processors, modulators, multiplexers, demodulators,demultiplexers, antennas, etc.), as will be appreciated by one skilledin the art.

Base station 102 can communicate with one or more mobile devices such asmobile device 116 and mobile device 122; however, it is to beappreciated that base station 102 can communicate with substantially anynumber of mobile devices similar to mobile devices 116 and 122. Mobiledevices 116 and 122 can be, for example, cellular phones, smart phones,laptops, handheld communication devices, handheld computing devices,satellite radios, global positioning systems, PDAs, and/or any othersuitable device for communicating over wireless communication system100. As depicted, mobile device 116 is in communication with antennas112 and 114, where antennas 112 and 114 transmit information to mobiledevice 116 over a forward link 118 and receive information from mobiledevice 116 over a reverse link 120. Moreover, mobile device 122 is incommunication with antennas 104 and 106, where antennas 104 and 106transmit information to mobile device 122 over a forward link 124 andreceive information from mobile device 122 over a reverse link 126. In afrequency division duplex (FDD) system, forward link 118 can utilize adifferent frequency band than that used by reverse link 120, and forwardlink 124 can employ a different frequency band than that employed byreverse link 126, for example. Further, in a time division duplex (TDD)system, forward link 118 and reverse link 120 can utilize a commonfrequency band and forward link 124 and reverse link 126 can utilize acommon frequency band.

Each group of antennas and/or the area in which they are designated tocommunicate can be referred to as a sector of base station 102. Forexample, antenna groups can be designed to communicate to mobile devicesin a sector of the areas covered by base station 102. In communicationover forward links 118 and 124, the transmitting antennas of basestation 102 can utilize beamforming to improve signal-to-noise ratio offorward links 118 and 124 for mobile devices 116 and 122. Also, whilebase station 102 utilizes beamforming to transmit to mobile devices 116and 122 scattered randomly through an associated coverage, mobiledevices in neighboring cells can be subject to less interference ascompared to a base station transmitting through a single antenna to allits mobile devices. Moreover, mobile devices 116 and 122 can communicatedirectly with one another using a peer-to-peer or ad hoc technology asdepicted.

Turning to FIG. 2, illustrated is a communications apparatus 200 foremployment within a wireless communications environment. Thecommunications apparatus 200 can be a base station or a portion thereof,a mobile device or a portion thereof, or substantially anycommunications apparatus that receives data transmitted in a wirelesscommunications environment. A paging indicator channel (PICH) can beemployed to notify a mobile device that it is possibly being paged. Themobile device reads another channel to verify the page. Conventionally,the mobile device read the secondary common control physical channel(S-CCPCH). However, the communications apparatus can employ the PICHwith high speed channels in addition to the S-CCPCH channel. Forexample, the high speed channels can include a high speed physicaldownlink shared channel (HS-PDSCH) and/or a high speed shared controlchannel (HS-SCCH). The communications apparatus can employ componentsdescribed below to facilitate timing and operation of the PICH channelwith high speed channels. The communications apparatus 200 can include apager 202 that can transmit a paging indicator to one or more mobiledevices and an HS scheduler 204 that can schedule and transmit dataassociated with the PICH channel for the mobile device corresponding tothe paging indicator.

According to an example, the communications apparatus 200 can employ thePICH channel in connection with the S-CCPH or high speed channels tofacilitate paging a mobile device and/or a plurality of mobile devices.This can occur, for example, when the communications apparatus 200detects data (e.g., incoming call, downloadable data, etc.) that is tobe transmitted to the mobile device. The pager 202 sends a pagingindicator to a mobile device on the PICH channel. It is to beappreciated that the pager 202 can send a plurality of paging indicatorsto a plurality of mobile devices. In one embodiment, the pagingindicator is set in a PICH frame by the pager 202. The paging indicatornotifies a mobile device that data is located on at least one otherchannel. The mobile device reads the other channels to verify that thepaging indicator actually designates a page to the mobile device (e.g.,that the data on the other channel is the mobile device's data). Thepager 202 can interoperate with both the S-CCPCH channels and high speedchannels such as a high speed shared control channel (e.g., HS-SCCH)and/or a high speed shared data channel (e.g., HS-DSCH, HS-PDSCH, etc.).When a paging indicator is received by user equipment or mobile device,the paging indicator informs the mobile device that it should expect toreceive more information such as a full paging message, other controlplane data or user plane data at a specific time instance (e.g.,subframe) on associated high speed channels. The association betweenpaging indicator and high speed channels can be determined by a set ofparameters established as a standard or signaled in overhead signalingmessages on common channels. The communications apparatus 200 canprovide the set of parameters that define scope, length and timing ofdata on the high speed channels. In one embodiment, the base station 200can announce the set of parameters on common channels. According toanother aspect, the base station 200 can announce a subset on commonchannels and the remaining parameters in the set can be announced pertransmission on dedicated messages (e.g., signaled on dedicatedchannels). Pursuant to an illustration, the set of parameters can betransmitted on, for example, a broadcast channel along with other systeminformation. It is to be appreciated that other common channels can beemployed. For example, the set of parameters or a subset thereof can betransmitted on the high speed shared control channel (e.g., HS-SCCHchannel). These parameters can be employed by the HS scheduler 204 toschedule data associated with the paging indicator on the high speedchannel.

The HS scheduler 204 can schedule data for a mobile device associatedwith the paging indicator on the high speed channel based at least inpart on the set of parameters provided by the pager 202. The parametersindicate a set of high speed shared control channel subframes or highspeed shared data channel subframes that are associated with pagingindicator on the PICH channel. For example, the set of parameters canindicate a number of subframes that a mobile device should attempt toreceive, a number of retransmissions possible in a HARQ scenario, adegree of multiplexing or interleaving between subframes destined fordifferent mobile devices and/or a number of subframes a mobile deviceshould monitor following successful receipt. The paging indicator set inthe PICH by pager 202 can indicate that a paging message, upper layersignaling specific to a mobile device or mobile device specific data isto be scheduled for the mobile device. The HS scheduler 204 can schedulethe paging message, upper layer signaling or device specific data in oneof the associated subframes on the high speed channel. The HS scheduler204 determines an appropriate time to schedule based upon an offsetdetermined for the lifetime of the channels.

Now referring to FIG. 3, illustrated is a wireless communications system300 that can generate a paging indicator that can be utilized to receivedata on a high speed channel such a high speed shared control channeland/or a high speed shared data channel. The system 300 includes a basestation 302 that communicates with a mobile device 304 (and/or anynumber of disparate mobile devices (not shown)). Base station 302 cantransmit information to mobile device 304 over a forward link channel;further base station 302 can receive information from mobile device 304over a reverse link channel. Moreover, system 300 can be a MIMO system.Additionally, the system 300 can operate in an OFDMA wireless network, a3GPP LTE wireless network, etc. Also, the components and functionalitiesshown and described below in the base station 302 can be present in themobile device 304 as well and vice versa, in one example; theconfiguration depicted excludes these components for ease ofexplanation.

Base station 302 includes a pager 306 that can transmit a pagingindicator 318 to one or more mobile devices, an HS scheduler 308 thatcan schedule and transmit data for the mobile device and associated withthe paging indicator 318. Additionally, the base station 302 can includea parameter selector 310 that can determine a set of parameters 322 sentto mobile device 304 on a common channel 320 (e.g., HS-SCCH, a broadcastchannel, etc.). The set of parameters 322 can establish a configurationfor mobile device 304 to utilize when receiving data on a high speedchannel 324 in response to a paging indicator 318. The parameterselector 310 can ascertain parameters 322 based upon scope and contentof data to be transmitted to the mobile device 304 as well asconfigurations of system 300. For example, the parameter selector 310can choose parameters 322 for the high speed transmission associatedwith the paging indicator 318 such that the parameters 322 conform tothe configuration of the system 300 (e.g., HARQ configurations, HS-SCCHoperation, HS-SCCH less operation, etc.).

Mobile device 304 includes a parameter analyzer 312 that analyzes theset of parameters 322 to determine how data will be transmitted on a HSchannel 324 in association with a paging indicator 318 and a HS decoder314 that retrieves data on the high speed channel 324 (e.g., HS-SCCH,HS-PDSCH, HS-DSCH, etc.) in accordance with the analyzed parameters. Inone example, the mobile device 304 can receive a paging indicator 318from the base station 302 on a paging indicator channel 316 thatindicates a possibility that the mobile device 304 is being paged Themobile device 304 can read another channel to ascertain if it is beingpaged and, if so, retrieve data on the other channel. Pursuant to anexample, the other channel can be the high speed channel 324 and thedata retrieved can be high speed data 326.

According to an example, the base station 302 can obtain data for themobile device 304. The data can be from another mobile device (e.g., avoice communication, a data transfer, etc.), a wired device on a networkcommunicatively coupled to the base station 302, a server and the like.It is to be appreciated that the base station 302 can possess data to betransmitted to the mobile device 304 (e.g. power control data,assignment data, etc.). The pager 306 of base station 302 can transmit apaging indicator 318 to the mobile device 304 on the paging indicatorchannel (PICH) 316 to notify the mobile device 304 that data is waiting.The timing of the paging indicator 318 can be based at least in part onthe discontinuous reception (DRX)/wake up cycle of mobile device 304.For instance, the pager 306 can set the paging indicator 318 when themobile device 304 wakes up to listen for pages every DRX period. Thepager 306 sets the paging indicator 318 in a PICH frame to notify themobile device 304 that high speed data 326 is scheduled in associatedsubframes of the high speed channel 324 (e.g., HS-SCCH channel or theHS-PDSCH channel). In one aspect, the high speed data 326 can include apaging message, upper layer signaling specific to mobile device 304 ordata specific to mobile device 304. Pursuant to an illustrativeembodiment, the paging indicator 318 set on the PICH channel 316 pointsto a set of associated subframes on the HS channels 324. Following thepaging indicator 318, the HS scheduler 308 of the base station 302schedules the high speed data 326 on the high speed channels 324 inaccordance with the set of parameters 322 established by the parameterselector 310 (e.g., schedules the information on the set of associatedsubframes). A timing offset between the time the PICH frame with thepaging indicator 318 ends and the beginning of a first subframe in theset of associated subframes is established for the lifetime of thechannels. The timing offset can be transmitted by the base station 302on the common channel 320. The mobile device 304 can employ the timingoffset to properly synchronize receipt of the paging indicator 318 andthe associated transmitted information 326 on the high speed channels324.

The base station 302 provides parameter selector 310 that determines aset of parameters 322 that can be transmitted as overhead signaling on acommon channel 320. The set of parameters 322 relates to how data 326associated with a paging indicator 318 is transmitted on a high speedchannel 324. The parameter selector 310 ascertains a first set of highspeed subframes (e.g., HS-SCCH/HS-PDSCH subframes) pointed to by thepaging indicator 318. This parameter, which can be denotedNUM_HS_SUBFRAMES_SET1, indicates the number of subframes that mobiledevice 304 should attempt to receive. According to an aspect, this valuecan be n frames where n is an integer value between 5 and 20, inclusive.In addition, the parameter selector 310 can determine a second set ofsubframes that the mobile device 304 should attempt to receive. Theparameter, NUM_HS_SUBFRAMES_SET2, indicates the number of subframes themobile device 302 extends it monitoring following successful receipt ofthe first set. In addition, the parameter selector 310 can determineparameters associated with hybrid automatic repeat requests (HARQ)configurations. For example, the parameter selector 310 can establishBLIND_HARQ_NUM_RETRANS that indicates a number of transmission repeatsfor the forward link only. Moreover, the parameter selector 310 canestablish BLIND_HARQ_STRIDE that indicates spacing in terms of subframesfor the aforementioned retransmissions. Pursuant to an illustration,forward link transmission can be repeated BLIND_HARQ_NUM_RETRANS timesevery (BLIND_HARQ_STRIDE+1) subframe(s). According to an aspect,BLIND_HARQ_NUM_RETRANS can be an integer between 0 and 7 inclusive andBLIND_HARQ_STRIDE can be established between 0 and 5 inclusive. Theparameter selector 310 can determine a floor and ceiling for the numberof HARQ instances based upon the chosen parameters. For example, aceiling can be given by(NUM_HS_SUBFRAMES_SET1/(BLIND_HARQ_NUM_RETRANS+1)) or a floor can beprovided by the same formulation. Moreover, the parameter selector 310instructs the HS scheduler 308 how to schedule HARQs. Pursuant to anillustration, each (BLIND_HARQ_STRIDE+1) HARQs are interleaved.Transmissions are back to back when the stride parameter is zero. Whenthe stride parameter is set to one, two HARQs are interleaved and so on.

In accordance with another aspect, the parameter selector 310 candetermine parameters based upon configurations of the network or otherentity. For example, regular HS-SCCH and HS-SCCH less operations can beemployed. However, the parameter selector 310 can indicate that bitexact HS-SCCH repetition is to be utilized to enable the mobile device304 to employ Chase combining. In addition, incremental redundancy HARQcan be predefined and the parameter selector 310 can utilize thepredefinition. Moreover, the parameter selector 310 can optimizeparameter coding in the common channel 320 to avoid combinations ofparameters that cannot be achieved. In addition, it is to be appreciatedthat the set of parameters 322 can be conveyed to mobile device 304during connection negotiation.

The mobile device 304, upon receiving the paging indicator 318, canretrieve a high speed data transmission 326 from the base station 302scheduled on another channel such as the S-CCPCH channel, the HS-SCCHchannel, the HS-PDSCH channel or other high speed channel. The parameteranalyzer 312 analyzes a set of parameters 322 on a common channel 320 todetermine the parameters established by the parameter selector 310 ofthe base station 302. The parameters 322 instruct the mobile device 304the subframes to receive and/or how the subframes are organized. Thetiming offset established for the lifetime of the channels indicateswhen the set of associated subframes determined by the parameteranalyzer 312 are scheduled on the HS channels 324. The HS decoder 314 ofthe mobile device 304 subsequently receives and decodes the subframes inaccordance with the parameters. For example, the HS decoder 314 receivesand decodes the number of subframes on the HS channels 324 indicated bythe corresponding parameter. Following successful receipt of the firstset of subframes, the HS decoder 314 monitors and attempts to receive asecond set of subframes.

According to another aspect, system 300 supports both HS-SCCH andHS-SCCH less operations. These operations are configured by the network.In HS-SCCH less operation, the mobile device 304 is configured with aset of transport formats. In addition, the mobile device 304 isconfigured with one or more walsh channels that can be blindly decoded.Moreover, pursuant to an illustrative embodiment, two high speeddownlink shared channels (HS-DSCH) Radio Network Transaction Identifiers(H-RNTI) are monitored by the mobile device 304 at all times. In oneaspect, the two H-RNTIs can be a common and dedicated H-RNTI.

Now referring to FIG. 4, an example timing diagram 400 that illustratesPICH to HS timing. The timing diagram 400 depicts relative timingbetween a variety of channels in communications system. For example, thetiming diagram 400 includes primary and secondary synchronizationchannels (SCH), any common pilot channel (CPICH), a primary commoncontrol channel (P-CCPCH), a secondary common control channel (S-CCPCH),a paging indicator channel (PICH), acquisition indicator channel (AICH)access slots, a dedicated physical channel (DPCH), a fractional dedicatephysical channel (F-DPCH) and HS-SCCH subframes. The PICH can beemployed with both S-CCPCH and HS-SCCH. As shown in the timing diagram400, S-CCPCH and HS-SCCH operate on different timings. Accordingly,offsets need to be determined to account for timing differences.

As the PICH can serve both S-CCPCH and HS-SCCH, the conventional timingneeds adjustment. Conventionally, the PICH served the S-CCPCH andprovided a timing τ_(PICH) that indicated the offset between the PICHframe and an associated S-CCPCH frame. In an embodiment, τ_(PICH) is7680 chips in duration. However, this duration after a PICH frame canalign with a middle portion of a HS-SCCH subframe. Accordingly, anadditional offset τ_(HS-SCCH) needs to be established. Pursuant to anillustration, τ_(HS-SCCH) is determined by the respective frame offsetof the PICH frame and HS-SCCH subframe as illustrated in the timingdiagram 400.

Turning now to FIG. 5, illustrated is an exemplary timing diagram 500that further depicts the timing between PICH and HS-SCCH. The timingdiagram 500 includes a PICH frame 502 that includes a paging indicatorpointing to a set of associated HS-SCCH subframes 504 and an offset 506that specifies the timing offset therebetween. According to an example,the first HS-SCCH subframe in the set of associated subframes 504 startsτ_(PICH) +τ_(HS-SCCH) chips after the transmitted PICH frame 502 thatincludes the paging indicator. Pursuant to an illustration, τ_(PICH) is7680 chips. Thus, τ_(HS-SCCH) can be determined as the offset between atime computed as the end of the PICH frame plus 7680 chips. Inaccordance with an aspect, τ_(HS-SCCH) is less than 7680 chips (e.g.,less than the duration of τ_(PICH)). According to another aspect,τ_(HS-SCCH) can be zero. Thus, τ_(PICH) is the only timing required andcan be relative only to HS-SCCH/HS-DSCH. In addition, it is to beappreciated that multiple PICH channels can exist that point to multipleor a plurality of HS channels (e.g., HS-SCCH and/or HS-DSCH).

Referring now to FIGS. 6-9, exemplary diagrams are depicted inaccordance with an aspect of the subject disclosure. For the purposes ofsimplicity of explanation, the examples illustrate timing diagrams thatinclude a PICH channel, a HS-SCCH channel and a HS-PDSCH channel. Eachblock in a row of a channel indicates a frame and/or subframe. It is tobe appreciated that FIGS. 6-9 are for illustrative purposes and thedisclosed subject matter is not limited to the scope of these examples.Those skilled in the art should appreciate how the timing diagrams canbe extended to other channel pairings, parameter combinations, etc.

In FIG. 6, an example 600 is illustrated that depicts PICH to HSoperation with two user equipment (UE) devices, UE1 and UE2. In example600, the parameter NUM_HS_SCCH_SET1 is 5, BLIND_HARQ_NUM_RETRANS is 4,BLIND_HARQ_STRIDE is 0 and BLIND_HS_SCCH_SET2 is 0. As shown in example600, UE1 wakes up 3 HS-SCCH subframes after the end of the PICH radioframe that includes the paging indicator to UE1. UE1 attempts to decodeany transmission on the associated HS-SCCH or HS-SCCH less channels(e.g., HS-PDSCH) for 5 subframes. The transmission is repeated for 5subframes. Subsequently, UE1 can employ discontinuous reception (DRX).Similarly, UE2 wakes up 3 subframes after the end of the PICH radioframe that includes the paging indicator to UE2. UE2 is configured toutilize HS-SCCH less operation and attempts to decode any transmissionon the HS-PDSCH channel for the next 5 subframes.

In FIG. 7, an example 700 is illustrated that depicts PICH to HSoperation. In example 700, the parameter NUM_HS_SCCH_SET1 is 5,BLIND_HARQ_NUM_RETRANS is 4, BLIND_HARQ_STRIDE is 0 andBLIND_HS_SCCH_SET2 is 10. Thus, in example 700, the UE monitors andattempts to receive 10 subframes after successful receipt of the firstset under the same conditions as the first set. The UE wakes up 3HS-SCCH subframes after the end of the PICH radio frame that includesthe paging indicator. The UE attempt to decode any transmission on theassociated HS-SCCH or HS-SCCH less channels wherein the transmission isrepeated over 5 consecutive subframes. If the UE successfully decodesthe HS-SCCH or HS-PDSCH transmission destined for the UE, it attempts toreceive packets over the next 10 subframes.

In FIG. 8, an example 800 is illustrated in accordance with an aspect ofthe subject disclosure. Example 800 is similar to example 700illustrated in FIG. 7. However, in example 800, the PICH is aligned withan S-CCPCH channel. The S-CCPCH channel is not aligned to the P-CCPCHradio frames.

In FIG. 9, an example 900 is illustrated according to another aspect ofthe subject disclosure. In example 900, PICH to high speed operation isdepicted with two UEs, UE1 and UE2. In example 900, the parameterNUM_HS_SCCH_SET1 is 12, BLIND_HARQ_NUM_RETRANS is 2, BLIND_HARQ_STRIDEis 1 and BLIND_HS_SCCH_SET2 is 0. As shown in this example, UE1 and UE2wake up 3 subframes after the end of the PICH radio frame that includethe paging indicators to UE1 and UE2. UE1 and UE2 attempt to decode anytransmission on the HS-SCCH channel or the HS-PDSCH channel (e.g., theHS-SCCH less channel) for the next 12 subframes. The transmission isrepeated over 3 subframes that are one frame apart. As depicted inexample 900, the subframes destined for UE1 are interleaved withsubframes intended for UE2. After receiving 12 subframes, UE1 and UE2can utilize DRX.

Referring to FIGS. 10-11, methodologies relating to providing HS timingand operation in relation to a paging indicator on a PICH channel.While, for purposes of simplicity of explanation, the methodologies areshown and described as a series of acts, it is to be understood andappreciated that the methodologies are not limited by the order of acts,as some acts may, in accordance with one or more embodiments, occur indifferent orders and/or concurrently with other acts from that shown anddescribed herein. For example, those skilled in the art will understandand appreciate that a methodology could alternatively be represented asa series of interrelated states or events, such as in a state diagram.Moreover, not all illustrated acts may be required to implement amethodology in accordance with one or more embodiments.

Turning to FIG. 10, illustrated is a methodology 1000 that facilitatesemploying a page channel to notify mobile devices of data on high speedchannels. At reference numeral 1002, parameters are determined that aretransmitted on a common channel to mobile devices to indicate how highspeed data on high speed channels should be received. In one aspect, thecommon channel can be a broadcast channel. It is to be appreciated thata dedicated channel can also be employed. For example, the Pursuant toan illustration, the high speed data on the high speed channels isassociated with a paging indicator on a PICH channel. At referencenumeral 1004, high speed data is scheduled on a high speed channel inaccordance with the determine parameters. In one embodiment, the highspeed data can be control data on a high speed shared control channel(e.g., HS-SCCH) or user data on a high speed shared data channel (e.g.,HS-DSCH). For example, the parameters can determine the number ofrepeats of a transmission and the degree of interleaving between one ormore transmissions destined for distinct mobile devices. At referencenumeral 1006, a paging indicator is transmitted to at least one mobiledevice. Pursuant to an illustration, the paging indicator is associatedwith a set subframes scheduled on the high speed channel according tothe determined parameters. At reference numeral 1008, the high speeddata is sent to at least one mobile device. The high speed data is sentas scheduled in the set of associated subframes.

Now referring to FIG. 11, a methodology 1100 methodology thatfacilitates receiving high speed data following notification on a pagingchannel is illustrated. At 1102, a paging indicator is received on apaging changing such as the PICH channel. The paging indicator on thePICH can indicate that a paging message, upper layer signaling specificto a mobile device or mobile device specific data is scheduled on anassociated high speed channel. At reference numeral 1104, data on acommon channel is analyzed to determine parameters contained therein.The parameters can define how high speed data associated with the pagingindicator is scheduled on the high speed channel. The parametersinstruct a mobile device as to how many subframes to attempt to receive,the configuration of the subframes, and whether or not to monitorfollowing successful receipt. At reference numeral 1106, high speed datais obtained in accordance with the determined parameters. At referencenumeral 1108, additional high speed transmissions are monitoredfollowing successful receipt of the obtained high speed data associatedwith the paging indicator.

It will be appreciated that, in accordance with one or more aspectsdescribed herein, inferences can be made regarding selecting and/ordetermining parameters employed in a paging indicator to specify data inassociated high speed channels in a wireless communications network. Asused herein, the term to “infer” or “inference” refers generally to theprocess of reasoning about or inferring states of the system,environment, and/or user from a set of observations as captured viaevents and/or data. Inference can be employed to identify a specificcontext or action, or can generate a probability distribution overstates, for example. The inference can be probabilistic—that is, thecomputation of a probability distribution over states of interest basedon a consideration of data and events. Inference can also refer totechniques employed for composing higher-level events from a set ofevents and/or data. Such inference results in the construction of newevents or actions from a set of observed events and/or stored eventdata, whether or not the events are correlated in close temporalproximity, and whether the events and data come from one or severalevent and data sources.

FIG. 12 is an illustration of a mobile device 1200 that facilitatesreceiving a paging indicator that indicates data on a high speedchannel. Mobile device 1200 comprises a receiver 1202 that receives asignal from, for instance, a receive antenna (not shown), performstypical actions on (e.g., filters, amplifies, downconverts, etc.) thereceived signal, and digitizes the conditioned signal to obtain samples.Receiver 1202 can comprise a demodulator 1204 that can demodulatereceived symbols and provide them to a processor 1206 for channelestimation.

Processor 1206 can further be operatively coupled to a parameteranalyzer 1210 that can analyze a parameters received by receiver 1202 todetermine how data will be transmitted on a high speed channel inassociated with a paging indicator as described supra, for instance. Inone example, the paging indicator can specify that a paging message,user equipment specific upper layer signaling or device specific data isscheduled on the high speed channel. A common channel can transmitparameters that determine the organization and timing of the scheduledhigh speed data. The parameter analyzer 1210 can verify the parametersto enable the mobile device 1200 to configure itself to receive the dataaccordingly.

The processor 1206 can also be operatively coupled to an HS decoder 1212that can that retrieves high speed data on the high speed channel (e.g.,HS-SCCH or HS-PDSCH channel) in accordance with the parametersdetermined by the parameter analyzer 1210. According to an example, themobile device 1200 can receive a paging indicator associated with dataon a high speed channel and the HS decoder 1212 can receive and decodedata based upon the parameters received on the common channel. Pursuantto an illustration, the HS decoder 1212 can decode the number ofsubframes on the high speed channels indicated by the correspondingparameter.

Mobile device 1200 still further comprises a modulator 1214and transmitter 1216 that respectively modulate and transmit signals to,for instance, a base station, another mobile device, etc. Althoughdepicted as being separate from the processor 1206, it is to beappreciated that the parameter 1210, HS decoder 1212, demodulator 1204,and/or modulator 1214 can be part of the processor 1206 or multipleprocessors (not shown).

FIG. 13 is an illustration of a system 1300 that facilitates thatfacilitates employing a paging channel in connection with high speedchannels as described supra. The system 1300 comprises a base station1302 (e.g., access point, . . . ) with a receiver 1310 that receivessignal(s) from one or more mobile devices 1304 through a plurality ofreceive antennas 1306, and a transmitter 1324 that transmits to the oneor more mobile devices 1304 through a transmit antenna 1308.

FIG. 14 shows an example wireless communication system 1400. Thewireless communication system 1400 depicts one base station 1410 and onemobile device 1450 for sake of brevity. However, it is to be appreciatedthat system 1400 can include more than one base station and/or more thanone mobile device, wherein additional base stations and/or mobiledevices can be substantially similar or different from example basestation 1410 and mobile device 1450 described below. In addition, it isto be appreciated that base station 1410 and/or mobile device 1450 canemploy the systems (FIGS. 1-3 and 12-13),techniques/configurations/examples (FIGS. 4-9) and/or methods (FIGS.10-11) described herein to facilitate wireless communication therebetween.

At base station 1410, traffic data for a number of data streams isprovided from a data source 1412 to a transmit (TX) data processor 1414.According to an example, each data stream can be transmitted over arespective antenna. TX data processor 1414 formats, codes, andinterleaves the traffic data stream based on a particular coding schemeselected for that data stream to provide coded data.

The coded data for each data stream can be multiplexed with pilot datausing orthogonal frequency division multiplexing (OFDM) techniques.Additionally or alternatively, the pilot symbols can be frequencydivision multiplexed (FDM), time division multiplexed (TDM), or codedivision multiplexed (CDM). The pilot data is typically a known datapattern that is processed in a known manner and can be used at mobiledevice 1450 to estimate channel response. The multiplexed pilot andcoded data for each data stream can be modulated (e.g., symbol mapped)based on a particular modulation scheme (e.g., binary phase-shift keying(BPSK), quadrature phase-shift keying (QPSK), M-phase-shift keying(M-PSK), M-quadrature amplitude modulation (M-QAM), etc.) selected forthat data stream to provide modulation symbols. The data rate, coding,and modulation for each data stream can be determined by instructionsperformed or provided by processor 1430.

The modulation symbols for the data streams can be provided to a TX MIMOprocessor 1420, which can further process the modulation symbols (e.g.,for OFDM). TX MIMO processor 1420 then provides N_(T) modulation symbolstreams to N_(T) transmitters (TMTR) 1422 a through 1422 t. In variousembodiments, TX MIMO processor 1420 applies beamforming weights to thesymbols of the data streams and to the antenna from which the symbol isbeing transmitted.

Each transmitter 1422 receives and processes a respective symbol streamto provide one or more analog signals, and further conditions (e.g.,amplifies, filters, and upconverts) the analog signals to provide amodulated signal suitable for transmission over the MIMO channel.Further, N_(T) modulated signals from transmitters 1422 a through 1422 tare transmitted from N_(T) antennas 1424 a through 1424 t, respectively.

At mobile device 1450, the transmitted modulated signals are received byN_(R) antennas 1452 a through 1452 r and the received signal from eachantenna 1452 is provided to a respective receiver (RCVR) 1454 a through1454 r. Each receiver 1454 conditions (e.g., filters, amplifies, anddownconverts) a respective signal, digitizes the conditioned signal toprovide samples, and further processes the samples to provide acorresponding “received” symbol stream.

An RX data processor 1460 can receive and process the N_(R) receivedsymbol streams from N_(R) receivers 1454 based on a particular receiverprocessing technique to provide N_(T) “detected” symbol streams. RX dataprocessor 1460 can demodulate, deinterleave, and decode each detectedsymbol stream to recover the traffic data for the data stream. Theprocessing by RX data processor 1460 is complementary to that performedby TX MIMO processor 1420 and TX data processor 1414 at base station1410.

A processor 1470 can periodically determine which precoding matrix toutilize as discussed above. Further, processor 1470 can formulate areverse link message comprising a matrix index portion and a rank valueportion.

The reverse link message can comprise various types of informationregarding the communication link and/or the received data stream. Thereverse link message can be processed by a TX data processor 1438, whichalso receives traffic data for a number of data streams from a datasource 1436, modulated by a modulator 1480, conditioned by transmitters1454 a through 1454 r, and transmitted back to base station 1410.

At base station 1410, the modulated signals from mobile device 1450 arereceived by antennas 1424, conditioned by receivers 1422, demodulated bya demodulator 1440, and processed by a RX data processor 1442 to extractthe reverse link message transmitted by mobile device 1450. Further,processor 1430 can process the extracted message to determine whichprecoding matrix to use for determining the beamforming weights.

Processors 1430 and 1470 can direct (e.g., control, coordinate, manage,etc.) operation at base station 1410 and mobile device 1450,respectively. Respective processors 1430 and 1470 can be associated withmemory 1432 and 1472 that store program codes and data. Processors 1430and 1470 can also perform computations to derive frequency and impulseresponse estimates for the uplink and downlink, respectively.
